glad to hear that everything works for you now.
Of course you are right, changing this in an existing project is likely
to cause quite a bunch of side effects. I usually set wantobjects to
False right from the start, then it does not add much cost to use calls
like int(cget('size')) etc. Maybe "ad hoc" type-conversions as these have
an impact on performance in some situations, if really a lot of them have
to be done, but I never experienced any problems of that kind.

Michael
