I have a really ood problem. When I walk (Shift key pressed down) I can't change my direction to walk to the left. While I am able to walk to the right, and I am able to use the left arrow key in every aspect, I'm not able to move to the left.
And so that you get what I mean, imagine you're walking through Spikes and you change your direction "while" walking, you can go the right, but not to the left. As if the left arrow key becomes unable to use when I use the walk key.
In Tomb Raider III, holding the walk key while you're standing still, and then pressing a direction key, makes you strafe left or right, that works to. But using the direction keys while I'm walking has some kind of issue. And it's happening in all Three Games.

Has someone an idea what may causes this to happen? It isn't really gamebreaking, but still annoying.

Thanks in Advance!

edit: I just bought TR4 and Chronicles, and there it's the exact same thing.

Hmmmmm
What keyboard do you have, and how old is it?
Is there software installed with it?
I have TR 1/2/3 from gog, and they work fine with the 'walk' and arrow keys.

I use a Logitech G510, and it's about half a year old. It sounds like Keyboard Ghosting to me, but it works in other games, also Ghosting shouldn't be an issue with modern Keyboards.

Really strange, especially since walking left works. But Shift + Arrow Up + Arrow Left is not working...

Ghosting is a problem with every keyboard, unless it is a ps2 (not playstation, lol) connector kb, and mechanical keys.

Some keyboards have gotten around the membrane keyboard + usb ghosting issue, but they are usually limited to around the wasd keys, and space bar/shift.
I dont know of any membrane keyboard that has anti-ghosting around the arrow keys, except an old Razer keyboard, and that thing usually failed within a year.
:(

I get the same problem with keyboard except with the jump button not the walk button . I keep alt as button for jump and if I hold down jump while jumping forward and press left she won't do it however she'll go right. She will, however, veer to the left if I let go of jump. Happens on all PC TR games 1-5 for me. I have just ignored it however but walking seems even more annoying.
