Can't switch to WhatsApp

Thank you for this great app!

Can't alt+tab to whats app desktop app. It does not show on the list.

Equally "system informer" app, an utility like task manager does not show.

Bellow a screen shot with whatsapp details, produced by system informar

Glad you like it!
That is definitely a bug. Thanks for supplying window information for WhatsApp.
It's not entirely clear to me what the cause of this is, although I do see in that list a window class that is filtered out by cmdtab, in case you want to poke around and experiment with the code yourself before I eventually land on a fix.
