Hi Andy,

YES! There will be some points you should check:

1.) using Quickreport? Check out the temp-path! if it is too long you’ll get errors! You can fix it if you have the sources of QuickRep (see “reporting-charting” group)

2.) Win2000 fire “OnChange”-Events more often / earlier than WinNT4 / Win98. For example you will receive OnChange-Events of Combos or Edits while the creating-phase of the TForm… so check out, that you’ll handle them savely! Check for nil-pointers in TTree-Change-Events! Maybe add a simple bool like “bInit := TRUE” to the beginning of FormCreate and “bInit := FALSE” to the end – check for this in the change events.

3.) reading/writing registry? If so, check your users rights! maybe he hasn’t the rights to insert ODBC- or some other system-keys. You can run into problems if you just try to read it – if you have set the “CanCreate” option to TRUE!
