having a few issues with my mouse(y).

Wireless M$ product(with a wireless keyboard) that just worked perfectly from day one, for about the last 6 or 7 years.
Then one day, the mousey started to do funny things, mainly with the left click button. Changed batteries, tested batteries, all is good. But mousey still refuses to click, and I usually have to click about 2-5 times to do anything.. what's annoying, is that sometimes I click 'too fast' and it turns into a double click, and welll ... it's damned annoying(as the title alludes to).

Keyboard has been splediferous in all this time!

That was on WinXP. So I have no idea on what's changed, and just assumed that it was the mousey getting old and decrepit. A new mouse was acquired, another M$ wireless thing.. which integrates perfectly with the old hardware(kb and USB wireless dongle thingo), and this one was a higher end maouse with 'higher precision' optics and so forth.
Same effluence!

About a week ago, I then installed Win7 and the mouse has been the same. .. but this time worse!

All drivers have been updated, I installed Intellipoint to access the uber quick buttons, I uninstalled and re-installed, and so forth, and still the same thing.

Now(with Win7), as well as the having to click 2-5 times issue, the mouse pointer drags across the screen as it feels fit too! one moment it's gliding across smoothly and linearly, the next it decides it want's to slow down across any random part of the screen. No pattern to it(which is the most annoying part) sometimes small mouse movements cause a swirly stuttering, and other times it's OK.

I haven't made any hardware changes at all before the mouse started to act up(on WinXP), and the only thing I can assume is that there may possibly be an interference issue form one of my neighbors who are both 10 meters either side and of course there's the interference killing walls and bricks and suchlike to contend with.(so it's a long shot, but not impossible)

No other devices have been acquired/installed/or recently used either.

Using task manager, I see no performance issues, Win7 is running sweet and fast(with minimal use of resources.
Mouse is connected via a USB-PS2 adapter that came with the mouse as I had issues at first in using the mouse via a USB connection. It's been connected that way since day one, with no problems.
I tried to connect it via the USB port again, but it doesn't want to work(even though USB mouse is enabled in the bios).

Curious as to whether anyone else has had mouse issues and how they've resolved them, or any other tips and tricks that tech gurus may have too(ie. what and where else to start looking)

it makes net navigation a PITA, and I frequently give up early on, and just go out and slam another nail in the coffin.

The other PITB I'm having is that HP haven't yet released new Universal Driver for their printers yet, and the Win7 driver is basically useless(doesn't allow any of the advanced features that the HP drivers did, even though the HP drivers were overbloated.
Tried printing to a simple 4x6 print format, for my son and his images which ended up a monumental effort in wasted 4x6 photographic paper(he was trying to make personalised pokemon cards.
The paper itself isn't the issue tho, they came free with my last set of Canon printer inks!
And hows this for stupid marketing nonsense too: Canon had/have this photo printing kit called the Photo Value Pack(CLI-8) which comprises 240 sheets of 4x6 270GSM Photo Paper Plus Glossy, and the four photo ink cartridges, and it cost about $90. Each individual photo ink cartridge costs about $25-$30 depending on where you shop(we're talking genuine Canon ink here, not thirdparty stuff).


.. anyhow.. hoping someone has a tip for the mouse issues.
