QFileDialog::getSaveFileName() does not work correctly on vista

using :

Code:

---

QString filename = QFileDialog::getSaveFileName(this, tr("Save Preset"),"./presets",tr("pxml (*.pxml)"));

---

does work on windows xp well, however on vista, no lineedit, no texbox appears on the screen to input the file name, nothing. am I missing something here?

everything looks fine. did you try to look at Qt's bug-tracker?
btw, can you attach a screen-shot of this dialog?

as you can see there is no item to input the name of the file.. I've tried it in two different vista operating computers :confused:

filters and file types are also not visible ?

I realized that on the same computer, logging in with another account , I managed to see the correct version of the savedialog.
Although these 2 accounts are the administrator type accounts, one cannot see the correct version of that window :confused:

Possibly this:

describes a solution to the same problem?
