Gerald,
[...] There is a reason I coded it that way, [...]
I guessed as much, thinking "xx3rd" and "yy3rd" might well be invalid at that point (because possibly modified elsewhere). But an occasional peek into the source is far from enough to know what's really going on.
But sometimes it's good enough. I made the change and it seems to work fine as long as "maintain screen coordinates" is set to yes. I changed the default for this variable to yes, which makes more sense anyway. All I can say is that it made sense at the time. Thanks.
Glad you still find time to maintain Fractint.
I need to make it easier to zoom the screen size, since it has to be done by hand now. I would like to put version 20.5 on the streets as an official release. The docs need a lot of help and I'm sure I messed up the demo files with my last patch and the source restructuring. The release file will look like the current zip file, so if there are any files missing, they need to be added (duh!). Jonathan
