hi today my pd crashed three times during work. it always happened after about 10 or 20 minutes of working and when i was selecting some objects. i use a version, which i recompiled with vc++ 5.0 some of the error messages i got: pd.exe fehler in anwendung. (pd.exe error in application.) die anweisung in "0x10018334" verweist auf speicher in "0x00000001". Der Vorgang "read" konnte nicht auf dem Speicher durchgeführt werden. (the instruction in "..." refers to memory in "..." The process "read" could not be executed on this memory.) die anweisung in "0x10018489" verweist auf speicher in "0x4077542c". Der Vorgang "read" konnte nicht auf dem Speicher durchgeführt werden. Unbehandelte Ausnahme in pd.exe (pd.dll): 0x00000005: Access Violation of course i think this is a consequence of my compilation. but i dont know where i made the mistake. does the "nmake" ever show any error messages during compilation? for i got none... i use 0.35.11 and w2k. marius.
