I posted some information here 2 days ago, that was not approved by a moderator yet???

This probably won't be either but...

Mach3 version 3.43.022 has a serious bug that causes Mach3 to lock up when using the tool change macro (M6) from the 2010 Screenset. I don't know for sure, but my guess is that this bug is in all 3.43.xxx versions prior to 3.43.028, where it was fixed. You really should'nt try using any of these versions.

For Jazz, the routines probably don't work because the G31 probe commands need the parallel port driver (or motion device plugin) to work correctly. Perhaops the russian cards plugin doesn't support G31 properly?

I have a new PC with Windows 7 x64 at work that I can do some testing on, but I'm leaving on vacation in a few days and won't be able to check for about 2 weeks.

This is really starange. My guess was that it's a Windows 7 x64 issue, but you're seeing it on 32 bit as well???
There are about 750-800 2010 Screenset users, and I have no other reports of this.
