problems running exampels from Qwt

[JL]

Hi All,

I have successfully installed the Qwt module. However, I encounter the following error message when I try to run some of the examples....

Application Error
The instruction at "0x1000c043" referenced memory at "0x00000008". The memory could not be "read".

Only "sysinfo", "sliders", "curvdemo1", "curvdemo2" examples can be run without any problems while the rest of them all have this same problem.

Not exactly sure what's going on here......
Specs:
Microsoft windows Server 2003
Microsfot Visual Studio 2005
Qt 3.3.8
Qwt 5.2.0

Any help is appreciated !!!

I have QT 4.5.3 under ubuntu Linux and all is working fine. Maybe you try to install a newer QT Version? In Linux a can use 4.5.3 and older Versions parallel.

Qwt 5.0.x is for Qt >= 3.3.x.
