Window whiteout

[Graham Samuel]

Folks, I am completely foxed by the following problem. I can't find 
anything doing the Google searches or in the Revo documentation. So 
apologies if this is a well-known issue which I have missed.

This problem shows up on two different Mac G3s running Revolution 
1.1.1 under MacOS 9.2.2 (my usual development platform). Revo has 
plenty of RAM to work in (currently 72Mb). My monitor is set to 
Millions of Colors (screenDepth 32).

I've imported some stacks from SuperCard using the tools provided by 
the Revolution folks (of course these stacks were windows in 
SuperCard). One of these stacks (containing just one card) has been 
successfully imported with all its graphics - that's what I thought 
would happen for all my stacks and cards. However, now if I open any 
other translated stack and show say the first card (doesn't **have** 
to be the first), all I get is a window with the correct title bar 
and an absolutely white interior with no features at all: yet the 
Application Overview shows that there are many graphics and indeed 
some images on the card, and if I click the mouse at random on the 
tabula rasa, the Properties Palette shows that I am clicking on 
various objects. These objects include really simple things like 
rectangles: they have their visible property set on, they have a 
border, etc etc. I can change all the colours in the Color Palette 
for any of these objects so that not one colour is white, and I can 
force them to the front, but the result is still the same. I can't 
see the difference between the card that worked and the ones that 
don't.

If I use the Revolution tool palette to draw a new rectangle on the 
white page, I can see it, and I can adjust its size, curiously 
slowly; but when I delete it, the grc doesn't actually go away until 
I force a screen refresh by bringing another window to the front and 
then bringing my original window back. I have no idea if this problem 
is related to the (far more serious) first one.

I notice that if I open SuperEdit (the SuperCard editing environment) 
and copy one of these objects to the MacOS clipboard and attempt to 
paste it into a card in Revolution, I get some kind of paint image, 
rather than a field, grc etc. I am not thinking of this as a bug, 
since there can be no automatic right to expect the object to 
transfer unaltered - but the interesting point is that at least I can 
see the pasted object.

I really do not know what to do apart from laboriously reconstructing 
the objects on the various cards, which means that the transfer from 
SuperCard will turn out to be far more onerous than I guessed it 
would be.

Any help would be greatly appreciated
