The were installed in one batch using package manager on the Internal Flash.
quake-demo
quake-engine
doom-demo
doom-engine
This is part of the problem it does it a number of different ways.
1) You click the icon, you get the screen resize with the "Please Wait" text, it then returns to 640x480 with no other output.
2) You click the icon, the screen flashes, returns to desktop
3) You click the icon, see the splash screen of quake/doom the toolbar re-appears on side of screen and even after leaving it for 10+minutes the games do not start.
4) Annoyingly it works perfectly.
Im guessing it is a timing issue between the rotate/resize and the SDL starting, I have more success if I rotate from rotate menu then run quake-demo or doom-demo from the command line.
When they run the games run beautifully though.
I will have another play at lunchtime and see if I can work out what is going on, I know SDL is segfaulting in at least one of the cases.
If I get time I might backup my data and reflash, then I can monitor the difference between a default install and my working set of apps.
