I've got a problem that at least at first glance seems pretty serious.
The only message or thread I found in recent archives remotely related
was this:

but it didn't seem to get anywhere.
I work with fixed-width data-sets passed to a business partner and
returned with the prescribed processing done on it. I've been using
SciTE to work with my files since I got this job, having no problem.
Today, I discovered that SciTE (1.63) was opening my file blank. But by
"blank", I mean it replaced each character of the contents with a space.
No. Well, I don't think it "replaced" the characters, but it displays
them as spaces...
This file happened to only contain one fixed-length record. The records
are 5120 bytes long. Scite was showing one line of 5120 spaces. Only
after opening the file in Notepad did I realize that the problem was
with SciTE.
I can reproduce that, taking any file with around 5000 chars, replacing
the EOL chars with space.
Now, I regret to say that the info in the file is confidential, so I
cannot present it here as a test-case. I will attempt to re-create the
situation with some dummy-data tomorrow. But I wanted to throw this out
and see if this problem or anything related to it was known or
documented to any degree. Or is this one just "out there"? It sounds
like it is to me, but I'm going to try to reproduce it anyhow.
Scintilla has trouble to handle very long lines. Not only they are
displayed as spaces, but on my old computer, SciTE is slowed to a crawl.
This is a very well known problem, and very hard to tackle, because it
is related to a limitation of the underlying graphic system (limited
length of coordinate system).
Notice that even Wordpad (ie. RichText control) has a similar
limitation, as it forces wrapping of the line.
I have meet this problem when editing a large XML file (SVG data) with
very long lines (country shape paths).
The good news is that you can still see your data if you activate line
wrapping in SciTE. Althought it will be still very slow, on my
PII300/Win98SE, my whole system is slowed down when I do a simple
operation like moving the caret...
For such data, perhaps another editor, or even an hex editor may perform
better.
