IQANrun 6.08 bug on measure graph

I resized the windows with the graphique on a big screen (4k) at my office,

but now I'm disconnected to this big screen, and I can't see the line to resize the graphique view.

it's hidden at the top.

I tried to resize the windows over my laptop screen (FHD) but I can't show the line to resize the graphique windows.

I just found a similar screen, so I could resize the windows and now have access to the line to resize the graphic part. 

I'm lucky to do not be on a plane or somewhere I can't connect a big screen !
