This is no doubt another *duh* question but I can't figure it out.
I have a display program which presents a subfile. Then it is supposed to put an information window over the top of it while other activity continues in the program. The window displays properly if I use the EXFMT opcode, but not if I use the WRITE opcode. At first I thought the window might be flashing so fast I couldn't see it so I tried stepping through with debug and nothing flashed.
I have the feeling this is another question with a simple answer, but so far the answer has eluded me.
