Those tables use a DMD made of 42 flashers and can't be moved with the mouse. It is a little tricky to move all those flashers and most of the time you need also to change the inclination of those flashers so they look squared. So the best option if you use FlexDMD also for desktop use. Find these lines at the beginning of the script:
' Use FlexDMD if in
FS mode
Dim UseFlexDMD
If Table1.ShowDT = True then
UseFlexDMD = False
Else
UseFlexDMD = True
End If
And change The False to True:
' Use FlexDMD if in
FS mode
Dim UseFlexDMD
If Table1.ShowDT = True then
UseFlexDMD = True
Else
UseFlexDMD = True
End If
Now the table will use FlexDMD and can be moved and resized with the mouse.
Newer tables, for VPX8, this DMD can be changed back and forth using the F12 menu. For desktop use I prefer to use my DMD because it looks better and the table starts up much faster, which is important to me mostly when testing the tables 
But if you have not updated yet to VPX8 you should do that, remember that VPX8 was released 1 year and 4 months ago
And you are missing some very good tables
