Amazing how you allways manage to come up with a fix for every small or less small issue that we experience. Great! Thanks a lot!

Agreed, Mike does a great job in fixing all these little issues.  Not helped by Google moving the goalposts, seemingly at every release of the OS, plus the huge number of marginally different versions of the OS that have been tweaked by the tablet manufacturer. 

Personally, I think Google missed a trick here.  By allowing manufacturer specific versions of the basic OS, it has made app development just that bit more difficult.
