FYI: I found that it was necessary to unzip the self-extracting exe file for webpack 7.1 and then run 'wine setup.exe'. If I tried to run 'wine WebPACK_71_fcfull_i.exe' wine would report an error about the exe not being a Win32 executable. So first run: 'unzip WebPACK_71_fcfull_i.exe' and then run 'wine setup.exe'. (thanks to Uwe Bonnes for pointing this out)
Also I found a hint about the GUI in the Windows version of webpack 7.1 by doing that unzip: There is a dll file called libQt_Qt.dll that gets extracted. This seems to hint that the Windows ISE 7.1 GUI is based on Qt. If so, then why doesn't the Linux version seem to be Qt-based (they still seem to be using WindU)? Maybe this is an indicator that there will be a Qt based GUI for the Linux version soon (that would be a good thing).
