Death by RefreshGadgets

[Mun-Kew LEONG]

Dear folks, I'm new to this net (posting, I mean - I've read everything
I could lay my eyes on in the net). I've been working/hacking/playing on an
Amiga for 5 weeks now, developing software for a course this fall. One of the
more basic things I'm doing is a simple proportional gadget, emulating a
slider with a little IntuiString gadget below that prints out the current
slider value. I have FOLLOWMOUSE set in the proportional gadget, and each
time I get a MOUSEMOVE event, I update the IntuiString buffer and Refresh the
gadget (of course, only if the value has changed).

Unfortunately, after a few clicks and moves on the proportional gadget knob,
or even fewer on the sizing gadget, the system hangs and I get me a GURU
message. I've managed to isolate the problem - it hangs during a RefreshGadget
call. Replacing the call by printf statements, or (as I'm doing now) a sequence
of graphic Move and Text commands, works fine.

I was just wondering if anybody else has had similar problems. I've compiled
the source under both Manx and Lattice, and both die though it takes longer on
the latter. I would really appreciate any feedback from the net. Thanks.
