I'm still seeing this glitch, sometimes a few times a day (leading to lost development time, since I now compile twice with each change to be sure the changes are 'caught'), anyone find a solution yet?

EDIT: I see now that you mentioned it was a task.

What else is running? Is another task also using debug.print without a semaphore?

On a related note (which might be normal, though) sometimes the IDE tries to download a program that couldn't have compiled, since there were compilation errors. For example, there was a "missing (" error, and yet the focus quickly changed from the Output window to the Debug window as the ...

There are sufficiently sensitive accelerometers. For example, this one would be able to sense the vibration if you go that route:

I captured this glitch on video. The following occurred: (1) code changed, then saved. (2) F5 was pressed. (3) code (from somewhere) downloaded and verified. No compilation process is seen on the video, although it may have compiled the first time before I started filming. (4) The program downloaded...

Thank you; I neglected to mention that this indeed fixed the issue, so hence this much delayed reply.

I have since removed the F7 button from my keyboard, to ensure that I'm hitting F5 (compile + *download*) and not just deceiving myself and others:D I still see this phenomena and have basically eliminated any human error. Maybe the compiler compiles an older version before it saves on hitting F5, o...

Woops...I didn't realize ZBasic supported goto, but I should have since it's vb based (and looking at it now, there it is in the docs). Hence the assumption that labels was for use with asm GOTOs. Thanks for the clarifications.

Ah...of course. Thanks.
I guess labels are supported for compatibility with assembly.

Runtime error from same-line commands?

My impression was that two or more lines of code can be inserted on the same line, like so: CodeA : CodeB : CodeC However, when CodeA is a subroutine, it fails to execute, and CodeB is the first thing run. Here's an example, where x and a are bytes, and subA is a short subroutine. su...

If you bound the function you're fitting with, judging by how your data curve looks you should be able to get away with something substantially less than 8th order.
Also, have you tried an exponential? Attaching the data points to your post might be useful.

If I recall right, there were crashes a while back with the progress bar, so that has been disabled. If that issue has been resolved, I can re-enable it and see if it yields any insights. Either way, I definitely see this occurring. I just had a new program "downloaded" three times in a ro...

Occasional download glitch

About one percent of the time it appears that a newly compiled program has downloaded (1280n), but in reality it has not. Then I erroneously assume I'm running a revised program. Occasionally I notice that it's the same one, for example when a debug statement is outputted after downloading, and the ...
