There is a FMP13 memory leak bug, which occurs during the import of large files. This is a major bummer, as my clients on FMP13 cannot import their data into a new set of files.
The workaround is to use FMP12 to do the import.
My question is:
"Assuming the import process does not utilize any layouts that were created using FMP13 nor any programming code which only exists in FMP13, will using a copy of FMP12 to do the import have any adverse impact?" Of course, after the import is done, the clients will then revert to using FMS13 and FMP13.
