[Lazarus] Strange inconsistency between Linux and Mac TEdit Height

[Donald Ziesig]

Hi All!

I am sitting here with a Linux PC and a Mac in front of me.  I have just 
uploaded the Linux version of a program for my Granddaughter to github 
and cloned it to the Mac.

On the Linux box I have a TEdit control whose height is set to 65 pixels 
(the Font height is -53); the control height is consistent with the font.

On the Mac I have the same form, all of which is consistent with the PC 
except for the TEdit control.  The height of the TEdit is 22 (only the 
very top  of the text is visible).  The font height is -53 as on the PC.

I looked at the .lfm file and the TEdit data are identical on both machines.

I attempted to resize the TEdit on the Mac by setting its height to 65 
in the Object Inspector.  As soon as I exit the height field it returns 
to 22.  I tried to resize it graphically, but dragging the bottom handle 
is ignored and the height remains at 22.  Doing the same on the PC works 
as expected.

Even more interesting.  When executing the program, the TEdit starts 
with a height of 22, but as soon as I change the text contents it 
resizes to 65 and displays the results exactly as they appear on the 
PC.  It works properly from there on until I exit and restart the program.

Does anyone have an idea of how to fix this?

The github account is dziesig and the two projects (public) are 
"MagicLibraries" and "MagicArithmetic".  The problem occurs on the main 
form of MagicArithmetic (flash cards for my granddaughter ;-) ).

Thanks,
