the following code:

B4X:

        TravPic.mBase.Left = JobInfoPnl2.Width + JobInfoPnl2.Left + 2
        TravPic.mBase.Height = 100%x - (TravPic.mBase.Left + 5dip)
        TravPic.mBase.Width = TravPic.mBase.Height

in B4XPage_Appear leaves the picture offset.
rearranging the order of the 3 lines above (and swapping height and width) puts the picture in a different place.
Tested in design view in B4i only.

No, I should have mentioned that. Tried it. Did nothing.

Please upload a small project that demonstrates it.

I was unable to duplicate this in a small project and it is not critical at the moment so moved on...

Tip: in most cases it is a mistake to do such changes in B4XPage_Appear event. B4XPages are simpler than activities. You don't need to wait for this event to make changes. You can make them directly whenever you need.
