Cant Copy And Paste In Dreamweaver

i had the same problem because i installed dreamweaver on windows 7 and it worked perfect on my windows xp

so if you have dreamweaver installed in windows 7 , you have to run it as windows xp.

NOTE:
go to dreamweaver.exe, select properties, under properites, select the compability tab

you will see it says:
If you have problemswith this program and it worked correctly on an earlier version of windows, select the compabilitty mode that matches that earliers version.
