Hi
Actually it is not a a memory leak, When you do not assign the colwidth property, Delphi does not allocate anything to it. It just uses the DefaultColWidth to determine the width of columns when drawing. But when you assign something to colwidths it uses Realloc function to allocate and integer array for the widths of the columns. So no need to worry (As far as I know, may someone know about this more)You may ask where do I know? I have just look at the VCL source code for the grids.pas.
Regards,
Igor

But why does the memory monitor for delphi 1 shows a leak when assigning a new value to the colwidths property?

Dear ponti,
Do you have a source code for grids.pas for delphi1.0? If so send it to me and I check for you (Also there is a bug in system.pas in delphi 1 in memory allocation, do you have the updates for delphi that fixes the problem. In this case all mem allocations may resource have resource leaks.) Inany case here is my email
inter@kosgeb.tekmer.gov.tr
