combo box /drop down takes 3 clicks to open

i dont know what i did but for some reason now, my combo box takes me 3 clicks to get it to activate.

anyone have any ideas as to what i should check that would cause something like this?

Hi andrew, no idea but a sample would help.

hi Fred,
thanks for the reply
attached are the files

The directory combo opens on the first click for me in AutoCAD 2010 on Windows 7 64-bit.

It's also a single click for me. Are you using 6.0.0.16?

hhhmm what do you think it could be?

no sir,
im using 6.0.0.15

i found the issue.

i use dual monitors, and i have the ribbon undocked and displaying on the second monitor and i also have the dialog box opening on the second monitor and when the ribbon is opened i get this issue with the dialog box, but if i close the ribbon the dialog box works as it should.

thanks for the the confirmation
