Skillbooks&CO, Apples&Alchemist, Invalid Pointer, BaM Skill Reset

I always seem to come here with a heap of questions, never one at once.

Skillbooks&CO:
[INDENT]Can I use a skillbook if my skill's level is (3+2) or (13+2) because of Combat Orders without encountering any problems? (It not 'taking' and eating my skillbook alive, specifically)[/INDENT]

Apples&Alchemist
[INDENT]I know that Alchemist affects the duration of Onyx Apples, but does it also increase the potency?[/INDENT]

Invalid Pointer
[INDENT]Getting this a ton this patch, is there something I can do to fix/prevent? Failed a CWK earlier because I got it when I was carrying the staff to the drop point. If it helps: Win7 64bit 1024x768 Windowed Mode[/INDENT]

BaM Skill Reset
[INDENT]I noticed Fiel said that Body Boost gained the requirement of points in it's hidden counterparts this patch (an effort to kill the glitches around it?), when I look at my skill list it's greyed out, but totally usable (I had it maxed before), if nexon holds another hot time event or whatnot and I SP Reset, would I be boned? Or could I add points to the skill without issue? Threw the last reset on my DB out of fear.[/INDENT]

Alchemist would only increase the duration of an Onyx Apple.

and yes you would be boned as you put it for the body boost and trust me im hateing the inability to add into bodyboost on my BtlM

Can't use skillbooks until the base number of points in the skill meets the requirement.

Sweet, thanks for the answers.

Last remaining question is Invalid Pointer, any tips on that?

I'm running Win7 64bit 1024 window mode too. I haven't gotten that many Invalid Pointer errors. A few but not many. Try reinstalling Maple and update video/sound card drivers. You can use Device Doctor to help find the latest drivers.

Not saying you do that sort of thing, but just in case, use clean .wz files

Using clean files, updated drivers. I'll redownload tonight just in case that's the issue.
