Did you check in Synaptic to make sure you had the "wine1.2-gecko" package installed? If it is installed and you're still having issues you can run this command in the terminal: "rm -rf ~/.wine" (without the quotation marks of course) and then run the "Configure Wine" program. If you installed WINE using Synaptic you can do this by clicking "Applications -> Wine -> Configure Wine". When you do this WINE will automatically re-create the "~/.wine" directory and place a fresh copy of all the DLL's in it. Then just re-run the installer for your program. Normally this clears up any issues I'm having with Gecko. -p.s. I'm also running Ubuntu 10.04[/quote]
