Slowly I have been reinstalling my Classic Apps which were all wiped after WebOS 1.3.1 update. Initially on trying to install everything at once, it kept crashing (and sometimes resets the Pre) but by selectively installing one by one (mine are mostly SkyScape medical programmes), it seems to be fine now. It seems if I disturb the installation (eg by turning it back on after usual 1 min switch off, either by sliding open, ON button or pressing the gesture button when slid opened), installation crashes. I just need to wait a lot longer (hence why safer install 1 at a time).

Also, am still getting Certified and Not Certified messages (latter especially with SkyScape which works fine and should be Certified!)
