Prevent multiple PickFolder windows

[dma]

Hello,

I have a button on a userform that opens a 'Session.PickFolder' window. If you keep pressing the button it will open multiple windows.

What would be the best way to prevent this behavior and open only one instance regardless of how many clicks?

Thanks.

maybe use API to check if the PickFolder window is already open.
set the window to Foreground if it does, otherwise open new instance.

I'll try that. Thank you arnelgp.
