WPF screen refresh problem

[Griff]

Hi

I have a WPF application (VS 2008; .NET 3.5) which has several tab controls
and listViews.

When I start the application, it start in normal "window" mode. I can click
between the Tabs and it's reasonably responsive.

However, I've made the window resizeable.

The bigger the window appears, the slower the window responds to my clicking
on tabs - the slowest is when the window is Maximised.

Is this something peculiar to WPF - I hope not!

Thanks

Griff

How beefy is your computer? Is the program doing anything behind the
scenes that will be taking away resources? Have you tried building the
release version and running it without a debugger attached?

Turns out that the bitmaps take a long time to calculate, so getting rid of
them improves things no end.
