caption: blank

hogi

After running

caption("my text");

sometimes the window is blank:

When I run the same code again, the cation text is visible.

Up to now I could not find an explanation when a caption text is displayed and when it's not.
Did anybody experience the same thing ?

No idea if it's a similar RC, but I have an issue just like that when running dense code -- since JMP is single-threaded it doesn't allow for the GUI to update properly.

For my code, doing this works:

caption("my text"); Current Window() << Inval << Update Window;

Another possible solution would be to add a "Wait(0)" statement after the caption code.

caption("my text");
Wait(0);

Thanks, nice trick - seems to work.

Interesting that refreshing a window also refreshes the content of the caption.

The only drawback: one needs an open window for it to work.

Is there a similar command which also works if no windows are open?

Good question -- I've never ran JMP without at least one window open, so I'm not sure

Same for me

But 5min after rolling out the bugfix I noticed, that you cannot take for grnted that a window is open on every system ...

And I noticed that even with a few windows open - there is an issue
... if the current Jmp window is no "window" - which seems to be the case for the Home Window and the Window List.

Just install the attached AddIn and try to run AddIn/Current Window() - first from a script, report or table window and then from the Home window.
