When I click the "Launch/Run/Whatever" button (the rocket ship), another QDK window opens up. Ho hum.

Sounds like somehow QDK has associated itself with .ASL files in Explorer.

To fix this, start Quest, click Tools, Options, Other, then Restore File Associations.

Edit:

This doesn't work. I did that in QDK but the same thing happens. I click Launch and another Quest Text Game Editor thing opens up. I found I can only play my games if I manualy go to the folder I saved them in a chose to "Open With > Quest"

<-- Angry Chinese Smiley is not Amused.

Seems I havn't gotten a reply because editing posts doesn't make the category appear to have a new post. So yeah.

Well, 2 ways to go about this:

Go to directory, shift+right click ASL file, click "open with..", select the quest application and also tick the "always open with this app". Then hit OK.

Go up into "view" at the top of the folder, and go into a settings menu there.
Unfortunately I don't use windows so someone else will need to fill this one out.

To get that 'always do this' option (as Tron said), right click, 'open with', select 'other', pop-up select quest and click the tick box near the bottom.

Thanks you guys.
