Hello all,

An Xbase++ GUI application created with Xbase++ version 1.90.355 might break 
after the middle mouse button was clicked and the wheel was moved. Maybe not 
at first time, but if we keep trying it breaks.

This has been observed when:
- Operating System is Windows XP SP3
- having a PS/2 mouse and the mouse driver: PS/2 Microsoft
- the application uses a Windows manifest file.

The application does not encounter this problem when:
- the application does not use a manifest file
- the mouse driver is not Microsoft
- the mouse is wireless
- The Operating System is Vista or 2000

If anyone could try or give me a reason for this, i will thank you
Best Regards,
Paulo Pinheiro

Paulo,

The most obvious reason would be that the Microsoft Mouse Driver is 
faulty and isn't working as expected, at least not with your mouse.

The most obvious solution is to change mouse drivers!

hm ... i did have XP sp3 and a "original" M$ PS2 Mouse but with 2 Buttons 
and Wheel.
if i click on Wheel (!!!) i got "nButton = 4" which is the same as "middle 
mouse button"

   cEventName := "Click"
   xVar       := oWmp:isEventPublished(cEventName)
   IF xVar <> Nil
      lSuccess := oWmp:SubscribeEvent(xVar,{| nButton,nShiftState,fX,fY | ;
                                             IF(nButton = 
4,PostAppEvent(xbeM_MbClick),NIL)})

i do use a lot of :Wheel and use Manifest (and a lot more) so i do not think 
it is a spezial
v1.9.355 Problem ... should be same with older Version ?

I don't know. I haven't tested.

On my Dell Precision with XP SP3, using a Dell (Logitech) PS/2 mouse 
with the Microsoft Mouse Driver, Version 5.1.2600.0, I can't get it to 
crash, no matter what I do. Have you tried a different Mouse Driver
version? It looks like yours might be defect.

My driver is also 5.1.2600.0, 01/07/2001, files i8042prt.sys, mouclass.sys
I believe is the standard driver of the XP

I new this was a long shot but, but...

In any case, i confirm that, in more than one computer i can simulate this 
behaviour.
I also confirm that using a mouse with a driver named as "HIC compatible", i 
cannot simulate this in my computer.

Best Regards

I can confirm, can't recreate, this problem as starting after I started 
to use Build 336 which had an interim fix for a problem I had.  Don't 
know if I still see it with build 355.  But, I did have the IDSC on the 
:wheel() method with build 336, never with 331.
