Hi,
original problem is described here: https://bugs.winehq.org/show_bug.cgi?id=34825 I have the same problem with running Nanocad 5.1. The file open/import dialog does not open with wine-1.7.39. I bisected the problem to commit: [bbf2cce16041e90d621a1f5889ea1bd760e21a0e] comdlg32: Do not modify dialog resource directly.
I reverted this commit on latest wine and that fixed my issue with file open dialog.
