I have no specific issues - I have not tested the code at this time. However, reading the multiple comments on the blog, along with no reply answering them, comes this:
MDI support. Custom border forms should support the effortless switch between MDI and SDI that .net implements for standard forms. Behavior should be identical, and translation of screen coordinates should be automatic (from screen position to clientarea position
within the parent). Child forms should be separately skinnable from the parent, and the parent should be skinnable as well.
If this has already been addressed, please notify me
and remove this ticket.
Thank you for this project - I will be reading through it extensively in the coming weeks.
