hello,

we have a problem with a patch not opening any more. it was working for years without problems. as far as i can see, the patch hasn't been modified at all, also the system hasn't been changed (no software or hardware modifications). the problem is on win xp and occurred with max/msp 4.5, today i updated to 4.6 to see if that by chance fixes it, but the error still occurs.

while max can be normally launched, when the patch is loaded, a window pops up saying

"Microsoft Visual-C++ . Runtime Error! Program: C:ProgrammeCycling '74MaxMSP 4.6max.exe . R6025 - pure virtual function call", and an "OK"-button. if i press ok, the dialog pops up again. After clicking 35x on ok max quits. that's it.

Trying to trash the preferences didn't help.

The patch is rather complex consisting of various subpatches. As far as i can see from the patcher windows opening, the error occurs in a subpatcher which is initially rather empty and is filled by using scripting max/msp objects, also i think javascript GUI objects.

what can i do?

thanks, -sciss-
