After migrating my Delphi application from XE2 to X10.1, I have a strange behavior at design time for one TForm
I can't enlarge it (with the mouse), it stays relatively small regarding how it was on XE2 !!!
There is no dimension constraint (all = 0)

Is it FMX or VCL form?

that's odd, is it an inherited form ?

check the form source .dfm > view as text
maybe you created this as an inherited form and put the restrictions on the parent ?

Found the problem : there was a groupbox on the form with incorrect position values (do not remember which one)
Now it is ok
