Client doesn't like custom shells (Windows) #1450

When I minimize or "close" the Bitcoin client, I can no longer open the client without having to terminate it and re-launch it. If it was minimized, the window will come back up totally white with no controls on it, and if it was closed the window will not open when I click the system tray icon.

I am using a custom shell in place of Windows Explorer called Xoblite, and it's based on BlackBox as far as I know. The previous client that I used, "Bitcoin 0.3.21 BETA", worked fine. The only other program I had a problem like this with was Skype before it updated recently.

Other statistics that might be useful, maybe: Windows 7 x64 Professional ATI graphics card

Is there any way I can get more information to help diagnose the issue?

As I've never used an alternate shell I can't suggest a thing here. Graphics drivers are up to date, as is the custom shell? You tried official 0.6.2 I guess? Can you verify the client works with the default Windows desktop.

I tried official 0.6.2, yes. I can confirm that it works with normal Explorer.

My graphics drivers and shell are updated, although the shell hasn't seen any updates for a long time.

Does it change anything, if you have an empty datadir? Is there anything in debug.log?

No change with an empty datadir.

The only error that seems likely to mean anything relevant is this: ERROR: FetchInputs() : ecd2af2deb mempool Tx prev not found ff6fe0fe69 ERROR: CTxMemPool::accept() : FetchInputs failed ecd2af2deb

Then again, that may just be network debug stuff.

This is almost certainly an upstream Qt issue.

The only suggestion I'd have is to play a bit with Qt creator and the show/hide logic in bitcoingui.cpp. Building bitcoin itself on windows is currently a hell though.

Closing this, it is too much of an edge case, likely an upstream issue, and almost impossible to reproduce.
