PB/DOS 3.5 -> Code become corrupted in the IDE during editing

[Basic Guy]

Someone tell me if this is a known issue or observation about PB 3.5 for
DOS. I've been using this for quite a few years (roughly 10 years) and
I don't see this happen all the time, but when it does happen - it's a
pain.

I was working on some code today and when I copied a line of code near
the top of the program and pasted it just under it on the next line. I
edited a few things on that line, and then hit page-down to get to the
last page of code. But some code on that page was screwed up, and some
was missing. And a few lines from near the top of the program where I
was cutting/pasting seemed to have been duplicated in place of the
missing code on the last page.

Is this a known IDE code/corruption phenomena?

I also have PB 3.0 or 3.1, and when I copied the source file to that
program's file directory and tried to edit it there, the same thing
happened. Is this some sort of corruption of the source file?

I had the same problem with v3.2. In addition to this it happened that all
the contents of the source file was deleted when I pressed F1 or ALT-F1.
E-mailed PB about it, but have never received a response.

Have you run or debugged your application in the IDE before you starts to
edit the source file?
It yes then your app probably have caused a memory override somewhere, and
that this most likely has corrupted the IDE's memory.
