1. IDE Editor Fix
Here's a small fix for the IDE Editor that should speed it up quite a bit:
In IDE_EDIT.EW, in the routines vscroll_Scroll and hscroll_Scroll, change
the code:
setFocus( mle )
editorDraw()
to:
if not hasFocus then
setFocus( mle )
editorDraw()
end if
This prevents the scrollbar from repainting the window if it doesn't have
focus. You should find the editor changes from slug-slow to nice and
responsive, no matter what size the window is.
There are compelling reasons to use an emulated editor, instead of a hacked
RTF control. Besides being more responsive and unlimited in size, it lends
itself to adding such nice things as context-sensitive hints. I'll look into
adding something like this.

2. Re: IDE Editor Fix
Hi David,
Used the patch you supplied but if I use the mouse to page up & down on the
scroll bar in never releases focus.
I mean that if I then use the cursor up or down key the whole page scrolls
and I can't type anything. If I don't use the mouse the editor really works
much faster.

Ooops, sorry. I didn't mean to imply that it was a final, well tested fix,
just that I had identified where the slowdown appeared to be coming from. If
Judith has tested my other 'improvements', she'll discover that they are
equally buggy (but still cool!).
I'll have a look at it.

I *suspect* releasing the focus flag before scolling will take care of this.
I'm sure there are other bugs lurking as well.

Yeah, it actually becomes quite usable. As I mentioned before, I think it's
a better route to take than to try hacking the same functionality into an
RTF control. If the new features ever get sufficiently debugged and
released, you'll see why.
The editor routine is stand-alone, so at some point I'll probably rip it out
of the IDE and incorporate it into the 'generic' editor.
Thanks, and sorry for the inconvenience.
