Client::OPMemorizeSpell

[Bonehard]

Hello all,
first i'am not sure where to post this under wich dev section.
So feel free to move to the correct section.

I'am working on some code and have find a strange bug and not sure where this comes from.

I have add some code to the Client::OPMemorizeSpell function.

	// Custom - Used for disabling scribes more than given number
	if (disableScribe)
	{
		// Count scribed spells
		int iScribed = 0;
		for (int i = 0; i < MAX_PP_SPELLBOOK; i++)
		{
			if (m_pp.spell_book[i] != 0xFFFFFFFF)
				iScribed++;
		}

		// check if we reached the maximum client can scribe spells
		if (iScribed >= numMaxScribeSpells)
		{
			Message(13, "Maximum spells scribed. Please unscripe some spells.");
			return;
		}
	}

The code is very simple it checks just if the user can scribe a spell or max number is reached. For example i disable scribing after 10 spells so that the user will get the message above.

The code works so far when a user tries to scribe a spell and reached the maximum scribe number he gets this message and the spells will not be scribed.

So far so good.
But on the client something strange happend.
The user get the info from server spell is not scribed but the gui is not responding anymore.
I can't click on npc's or door's.
Keys also don't work anymore so i cant open any windows like inventory.
I can open dialogs like inventory only over the menu.
Buttons stills works but it seems the gui is not responding anymore to hotkeys.
If i open one of the dialogs like inventory over the menu it shows up but it takes no input from mouse.
This happend to any menu i call over the menu.
I can click into the chat input window and still can type some commands.
So when i use the #zone command to leave the zone the gui seems to work like it should.
It only happend when i try to use the custom code i posted above.

Some more infos:
I compile under windows with visual studion 2013 in X64 mode.

The client iam testing at the moment is underfoot(steam).

Thanks in advance!!!
(Going to work now. Maybe i can respond later from work.)
