Dialog boxes appear and disappear

I have been working with Draftsight for a couple of weeks now and all was well until yesterday. Yesterday, when I double clicked on a block (edit attributes is the default command for double clicking in that case), the dialog box to edit the attributes would not appear. Today, that issue is fixed somehow, but now whenever I type FIND or use CTRL+F, the find dialog box does not appear.


Can anyone help with this issue?
