Flickering in Main Menu & Windowed Mode Bug

Okay.
I just downloaded Black Mesa, and I’ve opened it successfully once so far.
On the second startup, the ‘Loading…’ screen does not appear, and the screen is black with flickering bits of what looks like the Main Menu and the background in the Main Menu screen. It seems I CAN click things in that state - since I somehow managed to click ‘EXIT’ without seeing it - but without seeing anything, it’s virtually impossible to start the game.

The second bug occurs when I use the -windowed command in the ‘Set Launch Options’ in Steam or click on ‘Run in a window’ in the in-game Options (which I did on my first startup). When I do this via the ‘Set Launch Options’, my status color changes to green for a sec, then goes back to blue. In-game, the screen turns yellowish for a moment then the game crashes.

Anyone else experiencing this problem?

Erm- BUMP because I still can’t open Black Mesa without the screen freaking out.
