Xailer & OZ Software

Hello Xailers,
This is an old problem that happens here with us, the elements of the form is not shown as it should be, this problem happened on the xailer main window too.
We thought it was because of the windows 7 64 bits, but it happened on a windows 8 32 bits machine too.
It is an random error so its difficult to make an example, but it already happend on a clean new test project, and it only happens with xailer.
Error in Xailer:

Error in our program:

Mario,
it seems both are different issues. The old issue seems to happen when
the Xailer default resources are not linked correctly to the program.
This new issue is a problem in the controls painting process. It could
be caused by two reasons:
1) the program has reached the maximum GDI handles that windows allows
per a single process. Windows assigns upto 10,000 GDI handles per
process. You can view the current value at any time by using the task
manager. If this is the reason, it clearly means that the program has a
resource leak and has to be fixed.
2) there is a problem in the graphics card or in its driver. It's
specially important when using aero on Vista and Windows 7, where the
requisites a very high. It seems you are using a very high resolution
monitor, and you have aero activated. It's possible that you run out
your graphics memory card.
What graphics card model have you? How much memory? Are the drivers updated?
I have two monitors (1680 x 1050 and 1920 x 1080 pixels). Some months
ago, I had an ATI 5850 card with 512 MB, and the second monitor showed
painting problems some times, randomly. Now, I have a nVidia GTX 550 Ti
with 1 GB RAM, and I've never seen those problems again. So, in my case,
the problem was caused by running out of video memory.

Hello Jose,
I have monitored the GDI resources usage, and with our biggest form it reaches 950~1000 GDI usage, so i think that it is not a resource leak.
Our notebooks have a good specs, the one i'm using has this specs:
Core i7 Q720 1.6GHz
8GB RAM
NVidia GTS360M 1GB(dedicated)-4GB(System Shared) updated with latest driver(295.73)
Windows 7 Ultimate 64bits
I'm using 1920x1080 resolution.
I tried disabling aero and the visual effects, but the problem still occurs.

Yes, they are good notebooks indeed.

I still belive that it's a problem in the video subsystem, but I cannot
asure it at 100% for now. Currently, my main OS is Windows 7 32 bits,
although I already have Windows 7 64 bits in a second HD from which I
start some times. I'll continue researching and testing it. If you find
any track which can help us, please report.
