I dont think the error was very helpful because I forgot to update the MAP file...oppps. But there was this erro this morning that pointed to Sysutils and it looked like it was trying to access memory as per your comments below. We do use a few arrays, mainly Dynamic. Maybe these need to be set to nothing before after they are not used. Unfortunitly before I took over this project, someone had already been hacking at it, and I did have to fix a few variant issues. SO, maybe you are on the button Myles. ITs just a case not of trolling thru the nasty code and seeing what I can do.
