I just installed XE 18.104.22.168 which seemed to go OK. I did a clean solution and then a full debug build for X32 which appeared to go normally. This is a Quickwin application BTW.
When running under debug in VS2010 shell I am getting "first chance exceptions" for "Invalid handle exception for current stack trace". These are associated with every Fortran open statement, inquire statement and Quickwin routines that use a unit (eg open of a child window & setactiveqq...)
The units are always explicitly declared as 4 byte integer variables and are initialised with sensible numbers. Most of this is mature code that has been used for years.
The exceptions are all continuable and the program seems to function correctly by the way.
Any clue as to what might be the problem?
