Hello,
I am having a problem where my mouse cursor flickers between two cursor types (ex. the Arrow and IBeam) in certain situations. I originally found this to occur when I added a RichTextBox control into an otherwise blank Visual Studio WinForms project, run the project, add text to the control, selected some of the text, and then moused over the selected text. Every time I moved the mouse a bit, another "flicker" would occur (meaning it stopped flickering after I stopped moving the mouse).
I have also encountered this when I start up a Visual Studio WPF project during design time if I mouse over the divider between the form and the XAML (the cursor flickers between Arrow and something that shows that I can move the divider up/down or left/right, depending on context). This one does not occur in Visual Studio 2013 (as far as I can tell), though it uses a different cursor type for that action.
Things I've tried:
- Publishing the project (for the first error). The flickering persisted (though I didn't try running it on another computer).
- Getting help on StackOverflow: the results suggested that few others are encountering this "flickering"
- Using Visual Studio 2013 (I'm currently using 2010) -- no change.
- Attempting to download .NET 4 (but I already had it), so I told it to "Repair" -- no change.
Strangely (to me), the default RichTextBox behaviour in WPF is different than in WinForms; it doesn't suffer from the above "flickering" bug.
My question: what can I do to fix this?
I've considered uninstalling .NET 4 and then re-installing it - perhaps the "Repair" tool wasn't effective? But I don't even know if this is a .NET problem.
