I’m seeing an issue where the Tweetdeck window stays minimised all the time under Windows 7 RC. Restarting Tweetdeck does not force it to appear, it seems to be permanently minimised. Right-click Pin to Taskbar has no effect.

I can see the Tweetdeck application appear on Alt-Tab (and Win-Tab). When the Tweetdeck button is selected in the Task Bar the button appears to react normally – displaying selected colour, other application windows lose focus correctly etc.

To test Air I’ve installed Twhirl, which appears to be working normally. However, one difference between Twhirl and Tweetdeck is that Twhirl is minimising to the System Tray only. It does not show a Task Bar item, nor does it appear in the Alt-Tab list.

Other info: I’m running Windows 7 RC1 (build 7100) with a dual monitor configuration.

Anyone know of a fix for this? Please leave a comment below! Update: some helpful suggestions:

@martharotter: See a triangle image in the taskbar next to the time/date? Click to expand & click on TD icon from there. That worked for me

@EvertB: I have Tweetdeck running on Windows 7 without any problems. Maybe you should select “install as XP” option on the setup file?

@swhelband: Agree, Love win 7 but I’m finding the taskbar has real issues so far with dual monitor support

Update #1: Working – by complete fluke.

Missing my multi-column Twitter goodness, I installed Seesmic Desktop (it’s a more than capable replacement).

Then, after reading the suggestions above, I decided to give some of them a try. However, Tweetdeck was visible when I loaded it. So, did installing Seesmic Desktop force an update of Adobe Air?

Update #2: Hide and Seek

Ok, the above is not a permanent fix, it’s now failing randomly (playing hide and seek) for me. Here’s when it seems to happen and when it fails:

1. First install of Tweetdeck (from memory): appears correctly
2. Next run of Tweetdeck: minimised, does not unhide.
3. Next run of Tweetdeck: minimised, does not unhide.
4. [Install and Run of Seesmic Desktop (which is an Adobe AIR app)]
5. Next run of Tweetdeck: appears correctly
6. Next run of Tweetdeck: minimised, does not unhide.
7. [Run then quit Seesmic Desktop (does it reset AIR?)]
8. Next run of Tweetdeck: appears correctly
9. Next run of Tweetdeck: minimised, does not unhide.
10. Run then don’t quit Seesmic Desktop (does it reset AIR?)
11. Next run of Tweetdeck: appears correctly

My conclusion is that Tweetdeck is messing up AIR status and Seesmic is resetting it to a good state.

Other info:

• Dual monitors (2)
• nVidea 8800GTX Windows 7 build 7100.
• I’m not currently running Ultramon (it doesn’t properly support Win7 yet), wonder if that would improve the situation.
