Default Odd slow redraw on some PC's


I am having and issue with a VB.NET App that displays data derived from a database in a DataGridView Control. I am retrieving the data into a dataview and then setting the Grid.Datasource = oDView.

On most machines it refreshes the data cleanly and quickly as you would expect.

On one of our PC's it slowly poplulates each cell. Left to Right Top to Bottom. Some are saying that the video for other apps is being affected when my app is loaded.

I am out of ideas as to what could be the cause.

I am showing Aero when compiling on my Win7 32 bit PC.
Could this have anything to do with it?

There is one way to find out.
Turn off the Aero theme

You might also take a look at what is checked on these machines for visual effects:
Control panel > system > advanced system settings . > advanced tab >
performance > visual effects > settings button
will take you to this dialog box with a number of options under the visual effects tab.

Something else to try - WinXP compatibility mode under Windows 7.
It has a number of options in that dialog box.
Two of them are:
1.) Disable visual themes
2.) Disable desktop composition
See if running in WinXp compatibility mode with these two options checked does anything..

Default

The machines in question are Win XP 32 bit. All PC's have mid-range CAD rated video cards.

I will give your first two sugestions a try.
