3 characters, using PIP



Repeater config:

Using whitelist/blacklist atm. Have whitelisted 1-=, CTRL, ALT, SHIFT, and Q E Z V G. F-keys are not whitelisted.

Other details:
Currently have "hot character" switch bound to CTRL+F1-F3. On switch, ISBoxer is broadcasting a number associated with a /follow and /target macro on each client. This allows me to switch between characters without having to re-follow and re-target manually.

I haven't started configuring things in detail yet, so I've done a very basic setup using ISBoxer. I've created a team, put my chars in the team, set up regions, and the repeater. ISBoxer is configured to "force" EQ2 to the foreground as I understand EQ2 needs to believe it's in the foreground in order to process input.

Since I'm just using a repeater, I've been switching between "hot characters" using CTRL F1 - F3. When I switch, the other characters will, rather frequently, stop responding to input. In order to get them to start responding again, I have to switch to that character and spam some inputs. While I'm attempting to get the character to respond again, I can mouseover items in-game and bring up tooltips, but keyboard input and mouse clicks will not register. After a bit of mashing the keyboard, the character will usually start responding again.

I believe that either the Repeater is not working properly, and the "buffer" is overflowing, or that EQ2 is realizing that it isn't in the foreground and suspending input.

Has anyone run into a similar issue or have any input on this?

I've searched the forums but could not find any similar problems reported by other users.
