Condensation in windows and frame movement

[jackpot]

We have a couple of windows that have condensation in between the double glazed glass. Not only is this not normal it looks unsitely. Can anything be done to remedy it or is the whole glass shot and im looking at buying 2 new panes.

Also at closer inspection from the outside if i press the glass their is quite a bit of movement at the top of the frame. Basically the whole frame is not secure properly. How can this be fixed?

Thanks in advance

is it a sealed unit that has failed, or is it two panes of glass in a frame? treatment is different.

Worked out ho to upload pictures now so reviving this thread.
Will the sealed unit need replacing or can this be fixed. Ive heard of specialists drilling a very small hole in the glass and inserting a very small vent in the window. Any ideas?
