Sometimes when you click the text tool for the first time an exception will be raised and caught with this text (in debug mode):
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NullReferenceException: Object reference not set to an instance of an object

This would appear to be because the fonts aren't finished initializing or something similar. After closing the exception window you can type text but not change font size. The fix is probably to catch the exception earlier and subsitute the default font size. |

This would appear to be because the fonts aren't finished initializing or something similar. After closing the exception window you can type text but not change font size. If you change to a different font type and then back again, you can change font size. (Probably initialized by then.)
The fix is probably to catch the exception earlier and substitute the default font size. |
