Remarks on the IDM for Motif

Modification of .content or .navigable on an edittext may influence whether the cursor (caret) is drawn solid in another edittext. It should be noted that in an edittext with .navigable = false no input is possible on Motif.
The solid cursor does not allow any conclusions about navigation order or focusing of an edittext.
