(239/243) 4002 - Too short horizontal scrollbar in vertical pane

Could you attach a file that you see this issue with? I can't seem to reproduce this issue.

Thanks, the screenshot and file should be a big help, but I've tried your file and still don't see the problem like in your screenshot. What plugins do you have installed? Do you still have the problem if you start jEdit with the -noplugins option?

Plugins list:

Actually, this problem appears not every time I open this file (and other files), and I can not determine conditions to catch it.
With small window size it appears more often.

Without plugins it still present

Ah, so the scrollbar won't bring you all the way down to the bottom of the buffer anymore?
I get that sometimes too. This is because the text area is confused about how big its buffer is, or something like that, and I need to usually "reset textarea" (macros - misc) to get a textarea that works properly again.

It happens to me a couple of times a week.

I think this one is about scrolling left and right, the horizontal scrollbar won't go right enough to see the end of the line sometimes. I haven't seen the issue you're describing either. Do you have a way to reproduce it consistently?

Okay, I can see this bug regularly when I use the mouse to drag the corner of jEdit and resize it. The calculation for the size of the horizontal scrollbar is off both ways, sometimes it's not even visible when it should be, and sometimes it allows scrolling too far.

This is probably related to the fixes for #3957 and #3911.
