Hi
12 years later and I get it again after a year without getting it.
I think the "Recipe" is - you rename the stack and then do a build.
The system get's it's knickers in a twist (technical explanation).
The fix above from mark still works and to save people looking ...
Code: Select all
lock messages
delete stack "revCursors" of stack "myStack"
save stack "myStack"
unlock messages

Hi all,
I am getting this repeatedly when saving as standalone.
I also get strange cursor icons, or there is no icon at all.
Do I need a revCursors stack in my project when I save as standalone?
But why the error messaage: already in memory?
But why oh why am I getting also the stacks Color Chooser, File Selector, Page Setup, Page Setup Dialog, Print Dialog and Printer Chooser?
What do I need to do to restore the cursors to what I see in the developing environment?
TIA
Elly

Those stacks are normally added only to a copy of the mainstack when a standalone is built.
The recipe for removing them is above in an earlier post.
I'm very interested in seeing if we can reproduce this so it can be prevented.
@Lagi, is your recipe a reliable means of reproducing this issue?
@anyone: has a bug report been filled against this?

QCC shows nothing when I searched for "revCursors"

Thanks for checking, Craig.
Anyone with a recipe for reproducing this have a moment to submit a report for it?

Hi Richard,
I would'nt say its 100% foolproof because if memory serves, whenever I "savesas" to change the name (not the first time) and then I did a compile more often than not the problem surfaced - so I make sure if I do a "saveas" I exit LC and come back in - which is why I went for over a year without it happening.
Just decided to test my hypothyesis ... and it turns out to be a wild goose chase.
I took a single stack with maybe 25 lines of code , did a save as and tried to compile a standalone. It came back with that useless error of "there is a stack with the same name" Save, Cancel , Purge - which always seems to go into a loop whatever I press, but no cursor problem.
I then did the same for the main stack with thousands of lines and multiple stacks where this problem has surfaced before, and guess what? It compiled without a problem. I tried a second time (I don't trust computers
) still no problems. Then again I think I have only had the problem once in the 9X series - it happened multiple times in the 6x series.
Sorry for the false "recipe"
Lagi

Thanks for testing that out, Lagi. At least we can now rule out one hypothesis.
We're not seeing a lot of these issues, but just enough that I still wonder if it's either a bug in the IDE, or something the IDE may be enhanced to prevent.
As I see more cases I'll try to work with those affected to see what we can learn. So far it's only about three, free enough that it's not likely a simple recipe, but just enough to suggest some sort of workflow pattern.
