Thanks for the suggestion Bill.  However, I don't see how it can be
something to do with the disk.

In the case of 5.5, the border of an image disappears when the blendLevel
is altered.  This seems to have something do with the new layerMode
introduced in 5.5.

With regard to the 6.x series, I hadn't been doing any LC development
between June and the end of November.

I remembered last night that I'd seen that distinctive visual artefact, of
the clock moving from the start bar to the to top left of the screen, so I
checked back on my notes.  When I looked back on my notes, I found that I
got these crashes when I tried out 6.6.  In April I was working on an
entirely different kind of stack (no use of images or graphics).  My notes
show that 6.6 would hang/crash in just these unpredictable ways (even just
deleting a line in the script editor would cause these kinds of problems).
It seems that on Window 7, 6.7 still has these unpredictable problems.
I've been using this particular PC for a couple of years, with no other
application but Livecode behaving in this erratic manner.

5.5 was at least very stable while I was doing nothing with images (i'd
been using the 5.x series on this PC from 2011 until I tried 6.6 in
April).  With 6.6 and 6.7 it seems extremely unstable, regardless of what I
am doing.  I realise that others are recommending 6.6 to those with
problems with 7.0.  However, since no-one has drawn attention to the visual
inconsistencies with a scrolling field on Windows (see the bug report I
mentioned), I'm wondering if very few people are using LC on Windows.
Either that or there's some strange incompatibility between LC 6.x and my
PC.  I've checked the graphics drivers and there's nothing more up to date
than what's installed.

Regards, Bernard





My inclination would be to try all these versions out on another PC running the same version of Windows you are using at the moment: if you can repeat these effects then it is Livecode: if not, it's your machine.
