This is not the true description. Comdlg32 crashes out even if I cancel. Could this be relevant? X Error: BadWindow (invalid Window parameter) 3 Major opcode: 20 Minor opcode: 0 Resource id: 0x5a00001 X Error: BadWindow (invalid Window parameter) 3 Major opcode: 20 Minor opcode: 0 Resource id: 0x5e00001 I can run the program (Jammer Pro 6) as Win98 with the dll copied from there but even simply reading files with MIDI information chokes. I haver never been able to run MIDI programs in Win98 mode in wine. Problem started with the version of "wine-unstable" on Debian Sid and persists in 3.1.28. I do not believe wine upgrading caused it but that wine is running afoul of some other Sid upgrade on or around August 30.
