Saving a standalone application was working and now it doesn't. I don't understand why I have this alert :
A stack "revCopiedIcons" is already in memory. The Revolution UI does not distinguish staks which have identical names, so editing these stack files while both are in memory could result in data loss.
Since I got this message after opening my main stack, the standalone app can't be done properly and I have a long text error beginning with
There was an error while saving the standalone application ... lots of numbers & commas... revCopyIcons...
I do not remember I did add stacks or files.
