Text formatting bugs - unwanted changes

[skiwi]

I select several objects on a diagram.
Some have white text (and dark background).
Some have black text (and white background).

I want to increase the font size.
I click the Set Fond button.
I increase the font size, and click OK

The text colour of all the objects I selected changes (to white in this case).
This is unexpected behaviour, and not like the behaviour of any other software I use where only the "changed" attribute gets applied.

Interesting response from Sparx support

Our developer advised that this is currently intended behavior for this dialog.
I will submit a feature request on your behalf so that the ability to only apply the properties which have been changed is considered for implementation in a future release.

I hope the feature request will be favourably considered.
