TImage ERROR?? Not worthy of Display
Luke Skywalker
for my text output. Now If I create a TImage object on the main form I
can drag other windows over the display and it won't delete. But if I
move the same TImage object and code to a newly created form I get
unexpected results. Am I missing some code that I didn't see in the
book?

OK! THIS WORKS!! This code works and the Rewrite doesn't work at all!

Perhaps it's a matter of the properties, not a matter of code. AFAIR some
property exists, that tells the control to remember it's contents. Compare the
form declaration in Text format, to find possible differences in the settings
of the properties and event handlers.
