Reinstaling the .net and C++ framework is probabally is a good idea, since I don't know if having two versions installed simultaneously has an effect, only that it can't be good.
Microsoft Visual C++ 2008 Redistributable - x86 9.0.30729.17

I am the only one that has posted this problem, and probabally represent no more than 100 affected users, perhaps even fewer as my computer was polluted by ST's development software and their "BTW: pay us $5000 more to make the hardware and software you've allready purchased from us work the way we told you it would in the first place." strategy. It broke my existing gcc and VS instalations so that no code would compile and run on my machine without my paying their ransom.
There could be some lingering code bomb on my system may have snuck through the reformat/rebuild - though I thought that I had destroied all the binaries before archiving my projects.
I've wated a couple months before buying Dyson/Eufloria and can wait a couple more to actually play it. Though this is an interesting puzzle for me to poke at.
edit: reinstalling the .net framework did the trick, though there are now other
performance issues appearing in windows itself.
