Weird Menu Problem

[PeterHarmes]

Hi,

I'm not expecting an answer to this problem, just an idea where to start looking for an answer!!!

My application is made up of executables compiled with xHarbour commercial (June 2010) & FiveWin (11.09)

I have a starting executable (Main.exe) that then calls other applications. All applications start by opening a window with a menu.

If I start Main.exe and then click on an application (Systems.exe), the app opens, the window appears but as soon as i click on a menu, the application hangs (no error message)

If I start Main.exe and open another application (Accounts.exe for example) this opens ok, the window appears and the menu works ok. If I keep the accounts.exe open and then open Systems.exe, the menu in systems.exe works fine.

If i close everything and start with systems.exe, the menu works fine.

So it only fails if i open Main.exe & go straight to Systems.exe

I've tried renaming systems.exe and still have the same problem.

The problem only seems to happen on certain machines (i've seen this on a couple of my customers now) so I will try to see what is common with the installations.

Any ideas?

Best regards,

Pete
