Hi, I´ve made a workaround, by opening a blank window first, if there is not active sheet displayed in the mdi.

window activesheet
activesheet = w_main.GetActiveSheet()
if not IsValid(activesheet) THEN
    opensheet(lw_blank, w_main)
end if

After opening the original window the user has triggered, close this blank window.

It is not very beautiful, because the blank window flashes briefly, but it works correct.

Hi Luis,

Thanks for reporting this problem.
From the screenshot you provided, this issue seems to be a bug in the new feature Tabbedview.
Please report this issue to our ticket system: https://www.appeon.com/standardsupport/newbug so that it can be properly received and tracked.
Please also provide a sample PB test case (with PBT / PBL) when you submit it to the ticket system.

Regards,

PB seems to have problems with correct window size values when window open process is not finished.

I have also issues with not resizeable windows and opened a support ticket. But Appeon will not fix it.

Maybe your issue has the same reason.

You could try a workaround: In window open event POST a custom userevent (e.g. ue_postopen). In your event call the resize event with the parameters of current window size.

HTH,

René
