we use QT 8.2 in a VMWare to test our Windows application. We used the Activate Method a several times and it worked fine.
Window("Empirum Management Console").WinTreeView("SysTreeView32").Activate "Betriebssystem-Templates;GHOST;CGR_GH_MD"

After the upgrade to 9.0 the same scripts in the same VMWare fail. The Activate method will not open not the desired dialogs. We tried a workaround with "DblClick" the list entry but the dialog doesn't open up.
And we cannot select the entry and use "MicReturn", because our application doesn't support this.

Has anyone experienced this problem with 9.0?
Has anyone a suggestion for another workaround?

We activated the mercury support, but until now they weren't very helpful.
