I got the same Problem with my 4 years old ThnikPad X61T (7762-94G) and looking for a solution too. When I bought the Thinkpad I got a 3year warrenty and during this time, they changed the brezel of the screen, because it liftet a little at the angle.
Now, a couple of weeks ago, the bubble started at the upper left side of the screen and get more. There is no damage at the cover surface.
Is there a possibility to fix this problem?
And the picture of the bubble:

I am having the same problem right now.
5 little bubbles have appeared in my x61t 1400x1050. I called the support and they said a tech will come and replace the lcd.
is this a problem for all 1400x1050 LCDs? if it is then a replacement will still develope the same bubble 1 year later. And my x61t will be out of warranty.
If the gel just drip off, is there a way to seal it around the lcd? e.g. with stronger gels that will not melt at high temperature?
A replacement is surely fair enough, but I really want a end-solution.
X61t with 1400 LCD is the last generation of 4:3 monitor and I would like to use a few more years.

After digging into internet a bit, I have found that the most possible reason could be the high temperature from CCFL. That's why the bubble occurs mostly at the bottum of the LCD.

It's probably not just the heat from the body, but most likely from the CCFL.
The temperature could be very high and it's just behind the bottum of the screen.
You may also check your LCD part ID
then there is gel inside and it will get bubbles.
there will be no gel between.
I will wait for the replacement and hope it will be -100 version.
Otherwise I will try to replace CCFL with LED so that the gel will not be melt.
Maybe applying a new layer of UV-resin around the LCD which can sustain higher temperature will stop the original gel dripping off?

My LCD was replaced under warranty and the new one already had tiny bubbles at the edges. Therefore I applied a strip of silicone caulking at the joint where the front glass meets the metal frame of the LCD. Time will tell if my solution works.
I think the air bubble problem is a result of CCFL heat transmitted by the metal frame surrounding the LCD unit. Then there is the front bezel which is stuck to the front glass. So when you move the open and close and twist the LCD the bezel flexes and pulls the front glass off. As a result more bubbles occur between the metal frame and the glass. That's what I think.
For out of warranty cases: a drastic final solution could be prying the front glass off the LCD by using a heat gun and then cleaning the remaining gunk using lots of alcohol. Then putting the front glass back on using a strip of double sided tape around the LCD frame.
My two cents.

Thanks for your info. It's very helpful.
If I get the 101 version for the replacement, I will try to replace CCFL with LED. so that the heat will not be a problem. There is currently such solution and it's not that expensive.
I will give an update as soon as i can.

Forget about temperature. I had the computer on for several hours. The temperature on the screen where bubbles developed is (measured by a infrared temperature sensor) 25° Celsius which is room temperature.
But even if this were a cause, the thing is Ill designed. What do the Lenovo people say about the issue?
