In OpenBlocks-1.7.10-1.3-snapshot-426 (and also in previous 1.7.10 versions), I cannot select the sides of the Auto Enchantment Table and the Auto Anvil in the "Auto Extract", "Auto Drink" and "Auto Eject" parts of the GUI. Therefore, I cannot make them accept any liquid XP... Also tried it with only OpenBlocks installed, with the same result... Thank you for your reply...

I can confirm that v-sync is causing this issue. Very strange.

Thank you for debugging this one. Unfortunately, since we don't use any risky OpenGL magic in this part and I don't know enough about quirks in video drivers, so this one will probably stay unresolved.

I'm unable to reproduce. Please make sure you have most recent OpenModsLib version. Also, check logs for stacktraces (non-fatal) and other suspicious entries.

I am using OpenModsLib-1.7.10-0.6-snapshot-220... Btw, I have the same problem with OpenBlocks in Bevo's 1.7.10 Tech Pack (not just my own modpack)... Anyway, thanks for the reply, will try to check the logs...

After some extensive testing I was able to identify the cause of the problem. It appears if the V-Sync is turned off. If I turn it on, I can select any side of the block properly. Hope this helps...

this may be a closed issue but it is still a problem. and i have also found out that instead of turning on v-sync you can also turn your FPS down to 60 and it works. and FPS above that and it will not read your mouse clicks what so ever. so this may help a little bit

Hmm, that actually hinted me towards solution. Should be fixed in OpenModsLib snapshot 250.
