We are running Windows 2000... I suspected the GDI handles to be the
problem in the end, but what do I do? :S

For J - its for an industrial application printing on lottery coupons
at very high speeds. Every letter on the coupon is a small bitmap,
every symbol is a small bitmap, etc. Our customer tells us that they
can easily use 20 different sets of symbols ("fonts") in each job; a
font consist of up to 256 characters, all of which must be pre-loaded
for speed...

If I can't sort this out using TBitmaps I will have to redo stuff to
use home made "TBitmap"s instead, replacing the TCanvas with a normal
byte array or something... Will be a true pain as I will have to
program new draw methods myself :S
