When I change the Textsize of a selected shapenode and then resizeToFitText(scriptHelper1.getConstant("FitSize", "KeepRatio")), sometimes the node remains in an odd state:
The node is selected (the handles are visible), but the node is not resizable and not movable. The text is invisible.
But when I unselect the node, the text is visible and the node fits the text.
When i select the node again, the text becomes invisible, the node unmovable and not resizable. (though the mousepointer changes to move or resize)

This does happen sometimes. If it happens, it is when I choose a smaller fontsize.
When I go back to the original font, this add state remains, but I can see the original font when I deselect the node.

this is my code:
var _font = node.getFont();
var _style = _font.getStyle();
var _size = _font.getSize();
var nw_font = _font.deriveFont(_style, myNewSize);
node.SetFont(nw_font);
var succes = node.resizeToFitText(scriptHelper1.getConstant("FitSize", "KeepHeight"));

I tried KeepRatio, but that makes no different.

Also noticed: when this happens, the node becomes slowly smaller, as if animated.

Is this an bug or am i using fontssize in a wrong way ?

In my attachment some illustrations from this behavior.

Hope someone can help.

suspendRepaint solved the problem.
I love this forum.
Thanks Stoyan, great help.
