It helps when function gets called but quits for no reason, mostly due to On Error Resume Next on a file I/O function. I don't use OERN much(unlike me from a few years ago) but I use it for JSON-parsing as its pretty prone to crashing but often doesn't have much effect on how the code runs as it often crashes on unused parameters etc. And also for Form_Resize as it just defaults below 0 values to 0 without writing more code.
