MT4 Hangs

Yesterday my FXDD MT4 platform worked fine.
Today, when I right-click on a chart and select Indicators or Objects, MT4 hangs, nothing works. If I press ESC the MT4 platform comes back to life but I still cannot display the Indicators or Objects window.
However, I am able to select Templates successfully.
I made no changes between yesterday and today.
Any ideas.
Thank you for your help.

Shut down MT4 and start it up again. If that doesn't work, reboot.

Delete it. Download and install once again. I had this king of problem

Guess you have solved this now but I'll answer in case someone has the same problem.

No need to reinstrall MT4, the window has prolly opened off screen - I had this problem when I changed from 3 monitors down to 2.

If using Win7, hold down the Windows Logo key and then press right arrow until the window appears. Worked for me in Win7 - don't know if it works in other versions of windows.

Now I do have exactly the same problem whilst everything worked fine before.

mcdirt's suggested solution does not work on my pc, I am still on Windows XP. Before uninstalling/reinstalling, does anyone have a less drastic solution?

Thanks
