<<getting MS Access applications to run>> Sounds like it is only using the Access database format accessed by the Jet engine, you are still needing to debug the vb app itself not Access. look at http://wiki.winehq.org/FAQ#head-a37de3282d447376d2220d20a278ae52258551a4 or http://wiki.winehq.org/FAQ#head-16da35b6327024d6ea576e3678488b16862d0f5e alternatively if you have the VB app source code and own VB you can install it under wine and try debugging the actual vb code.
