--- Comment #2 from Tefnet developers developers@tefnet.pl 2008-04-18 03:43:41 --- I found out that it also happens with builtin hhctrl.ocx but you have to wait couple minutes (sic!) to release gecko engine.
Steps: 1. install gpstrack 2. open gpstrack with WINEDEBUG="-all,trace+mshtml" 3. F1, browse 4. close help 5. wait until you see in console
trace:mshtml:close_gecko
6. if you're lucky and it didn't crash, you can press F1 again and you'll get
"HTML rendering is currently disabled"
