I put the included squeeze converter on my Metro while the Con-50 was drying, and I bumped the pen a little bit once or twice on my desk by accident when taking it out of the drawer, and when I unscrewed the body of the pen, I noticed ink had leaked onto the outside of the converter from where it connects to the rest of the pen. Is this something I should worry about? The only reason I ask is because I thought the seal between the converter and the pen was supposed to be airtight even when bumped a little. Just didn't know if a little leakage is normal.
