Crippling CPU utilization bug related to mouse cursor when hover over any trap.

[BigSilverHotdog]

As title says, whenever I hover mouse cursor over any built trap it rapidly flickers between the 2 cursor icons and cpu usage goes to maximum and stays there until I move mouse cursor away.

I already tried to get an answer in the bug forum but nobody ever reads or posts there. I know dev is tiny (I've put tons of hours in both games and have been here since the very first release) but now I can't play either of them because of this bug. As far as I know, no other game is having any similar problem. I've updated to latest nvidia driver and my system used to play these two games without issue.

Very, very frustrating because this is probably my ALL TIME favourite TD series and I'm a massive, massive fan of the genre. Hope someone might have a clue about this bug because I know I'm not the only person ever to see it:

EDIT: I have managed to TEMPORARILY fix this bug several times, once by rebooting (which doesn't always fix it), once by closing all non-essential w7 related tasks in taskmgr (which also doesn't always fix it), and a couple of other times where I have no idea what fixed it.

It keeps coming back, but at least now i know I can have some affect on it.

Anyone have any further ideas? If I eventually trace it down I will update this thread again later...

EDIT2: I have FINALLY traced this issue down to the 2 NVIDIA display driver active processes, both of them "NVDisplay.Container.exe" -- if I end these manually the driver resets and DW/DW2 will then play normally (for a while).
