I tried this fix and my image immediately shrunk to around 22 MB. It had 
been far beyond 50 MB at times.

Thanks a lot for that.

I suspect that "normal operation" does not include debugging a lot, 
because this is exactly what we do very much: do the first things that 
could possibly work and see what the debugger tells you afterwards. Our 
App is far from being complex, no resources like images or the like, 
because we currently concentrate on teh functionality.

Being a VAST user for many years, I somewhat am used to using images 
with 50 MB and more, so maybe this is the reason I never really wondered 
if that's okay. I only realized that seaside images (VW) grow very fast 
(within a few hours of developing/debugging).

thx
