63 : Form controls (more precise: UNO Controls) in the drawing layer are ... prone to breakage, since they have some
64 : specialities which the drawing layer currently doesn't capture too well. In particular, having a living VCL
65 : window as child of the document window, and coupling this Window to a drawing layer object, makes things
66 : difficult sometimes.
67 :
68 : Below is a list of issues which existed in the past. Whenever you change code here, you're encouraged to
69 : verify those issues are still fixed. (Whenever you have some additional time, you're encouraged to write
70 : an automatic test for one or more of those issues for which this is possible :)
