Hi Giuseppe,
We made some /initial testings/ on an application of ours. It starts, HFSQL Standard is working, and almost everything in that DB application looks ok.
But we experience a "hang" in a give Window for some reasons - that can be anything (a control, some procedures, events, etc.) We did not take time to investigate, we only wanted to see how far we can go with no debugging efforts; and we only tested one application at this moment.
In Wine, you must install IE and some other packages. But to keep all that simple we simply bought CrossOver Linux Pro to ease the configuration. (www.codeweavers.com/products/cxlinux/)
So there are on our side some issues that we must be investigates, but overall it looks like it could work great. (The fact that WinDev applications are compatible with Win98 helps a lot concerning that. But I assume that some very high-level features could simply not work in Wine at this moment. I can't tell.)
I Hope this helps,
Alexandre Leclerc
