I had a wallet.dat file from long time ago ... thought I put in the wallet to check on the wealth and health.

I just loaded bitcoin-qt 0.8.5 and it's running on Win XP 32 bit. Replaced the wallet and re-launched bitcoin-qt. The flash screen is gone but the application never did come up. In place of the flash screen is a squarish rectangle that was last being displayed.

On the top right hand corner, bitcoin qt seems to be running. However, I cannot see anything other than that.

Any ideas what's going on?
