A client is getting an error message. Gendisplaymask. API call caused an exception. Unexpected system error has occured. This message doesn't always occur. Nor does it appear in the same place. I can't repeat it on my computer. I'm using Codemine. I'm not certain if it's a Codemine, VFP, or Windows error. Has anyone had this error? Any suggestions on how to fix it?

TIA
