Put EMPTY commands at stategic places in your code.

Try EMPTY after plotting.

1) I got IDL 3.5.1 for the PC a week ago. I haven't been brave enough to try
the editor. Under 3.1 it used to crash IDL and ERASE THE FILES. I could
never work out a pattern but I understand this happened when the file size
was a multiple of 64 or 96 bytes or something. RSI do not claim to have
fixed/improved the editor. It will have to be a lot better before I use it
again.
2) Never encountered this.
3) This, I think, is a consequence of the fact that IDL for Windows doesn't
do cooperative multitasking very well. (Have you ever noticed that screen
output that should be written at the start of a long computation doesn't
appear till the end? Ie. even IDL's own screen output is held up by the
computations.) I don't see any change in 3.5.

Try the following statement after the graphics command you want to
force to be displayed:
wait, 0
It usually works for me.

Does this mean that the command "EMPTY" no longer works??!
On a sort of related topic, is there anybody out there running 3.5 on a PC?
I was wondering if the following bugs had been fixed:
1) The built-in editor running out of space
2) Incomplete support for some font-related commands with Widgets
3) Non-standard behaviour in the Windows environment. Specifically,
version 3.1 doesn't seem to respond to ^C unless there is I/O to the
screen. Consequently, the only way out of a computationally intensive
mistake is Ctrl-Alt-Del. However, this frequently results not in the usual
Windows "Application is not responding, do you want to kill it" message,
but in an ungraceful crash out of Windows. This is irritating.
Please post any information about 3.5 on the PC, as I'd be very interested.

I haven't run into the first one, but the second gripe is real. It seems that
when you do an XYOUTS, the last character does not get plotted. When you generate
a postscript file, everything looks fine, though. I haven't found a workaround
yet either. Really sucks!
