I have run into that problem myself, I think. For me ... it is an intermittent issue ... and occurs only once in a while.
What I do ... is use a utility like Sizer (http://www.brianapps.net/sizer/) to resize the application. Sizer can even be used to move a window that is completely off screen ... to on screen ... by accessing the
Sizer menu via a right click on the app in the Task Bar.
I think the problem comes out of how we have implemented the saving of user settings (like window position and size). At some point, I would like to revamp that whole part of Snoop.
Try using Sizer and see if it helps you.
The user settings do get saved in the app.config file ... but Snoop makes the problem a little tricky ... since it injects itself into the Snooped process.
In other words, the position and the size settings for the app chooser (i.e. the thin blue bar that comes up when you execute Snoop)
are stored in the Snoop config file ... but the position and the size settings for the main Snoop UI (i.e. the property grid window that comes up when you Snoop an app) ...
is actually stored in the config file for the app being Snooped.
One thing that you can try ... if Sizer doesn't work for you ... is to go to your local user settings area and delete the user.config files for both Snoop and the application you are Snooping.
For example, for the released 2.7.0 version of Snoop ... the user.config file is stored at: C:\Users\plottsc\AppData\Local\Cory_Plotts\Snoop.exe_Url_svr3ea1awr4rmikpujw0xmksr1tpt4kp\22.214.171.124
Deleting the above file should revert the position and size information for the app chooser back to its defaults.
And to continue the example, the user.config file for the application I Snoop most often is stored at: C:\Users\plottsc\AppData\Local\Starkey\Starkey.Inspire.Host.Stan_Url_qxzblujf3qlnz4mqhww3tnfs1lvpcdqs\126.96.36.199
I work for a company called Starkey Laboratories ... and the assembly I'm Snooping is Starkey.Inspire.Host.Standalone.exe. Deleting the above user.config file should revert the position and size information for the main Snoop UI (and the other windows)
back to their defaults.
Hope this helps ... and sorry for the pain this issue is causing.
Let me know if you get around it.
