Odd behaviour in an MleText.

This was first noticed in a Sudoku "helper".  MleText "cells" were used to show 3 x 3 arrays of numbers.  When the font used in an MleText "cell" was changed from 'monospace 10 Normal' to 'monospace 10 Bold' -- to display one assigned number -- the numerals changed positions (and the program could not cope).  It was as if the size of the characters (or size available in the edit control) had changed.  The number 3 (top right in the cell) had been 'wrapped' over onto the second line etc, etc.

This did not seem TOO strange.  A bigger surprise came when the change PERSISTED after the original font had been restored.  The effect was seen even if the text in the box was very short when Bold was being used.  Therefore it seems unlikely that this was some weird 'overflow' effect involving e.g. scroll-bar code??  (Note: no scrollbars visible.)

< A stripped-down version of the program with 3 cells is attached for illustration. > (*** Sorry.  Can't attach it! ***)

Left-clicking on a cell produces a 3 x 3 array of numerals in Normal font (a 'tidy' 3 x 3 if 'Bold' has NOT been used).

Right-clicking produces a text in Bold.

The starter text in cell 3 (right) is "Short".  If my first move is to right-click on this, these 5 letters become bold, but they should not overfill the control?  If I follow this with a left-click, 'untidy' numerals are displayed - just like the cells with more chars - as if some mysterious overflow has taken place.

My original problem was solved by using the Bold font for a moment at the start of the program.  Then the program proceeded as before.  The altered cell layout was stable - so I could code for it. ---- Phil
