I had problems with the releases before 3296, but they have cleared up now.
There are some themes that screw up, but the Z1 glass theme is working great.
When the 3296 came out, I did a total uninstall(deleting all folders and files in the x86 programs folder, roaming folders, local and locallow; then, did a cleaning of the registry.). I install the app new and imported my bookmarks, contacts, and such from saves I did before un-installing.
Just upgraded to 3298 the other day and she has not crashed or locked-up.
The scripting problems are even gone.
