I can't write on my signs

[Archmuppet]

Hello to you tekkiters!

I have run into a problem, i can't write on my signs anymore.

Launcher/pack Version: Launcher v.0.5.4.4/ pack, Tekkit v.2.0.0 (i am not sure if this is right, but i am using the recommended build for right now, 2012-03-06)

Operating System: Windows 7

Version of Java: 1.6.0_29

Description of Problem: I can't write on my signs anymore, when i try i see the letters for about a sec and then they vanish. When i started the server ( i host a server on my pc for me and friends, with the latest server download there is today (2012-03-06)) i had no problem with this and i have tried to make a new server a few times, but after a while the same thing happens again, the text on my signs disappear.

Error Messages: N/A (i don't get any as far as i can see...)

thanks in advance for your help =)

(btw, tell me if i missed something that you needed to know)

Is there any redstone current switching in the vicinity of the sign? This reliably shows that behaviour.

Ah!

That was it, after some experimenting i found that it does not happen if I have vanilla redstone, but with redpower's wires you can't have a sign within 4 squares without the text disappearing.

Thanks for your answer milcondoin, it helped. It is hard to have a sorting machine without having signs to label my chests. =)
