I've played 2-3 games on Vassal now, and I consistently have trouble moving cards and figures from my player hand to the map window. I'm playing on a MacBook Pro laptop running High Sierra, and the laptop is from 2010. It doesn't seem to have speed or connection problems or anything, but when I try to move a figure from the Player Hand to the Map, it's only successful maybe 2% of the time. So it can work, but it often seems not to, and I don't want to make my opponents wait while I mindlessly spam-drag the tokens trying to get them onto the map as my frustration increases. Strangely, moving things from map to hand (or cards/figures/tokens to hand, for example) seems to always work with no lag of any kind.
I can sort of work-around it with a patient opponent by literally opening the cards/figures/tokens tab at the start of game, dragging each of my deployments onto the map, creating a figure, then deleting the "extra" deployment card. It's a chore, but Vassal games are a really fun and relatively simple way to train against good players. For friendly play and training, this is fine, because I can make my own room and basically be ready by the time an opponent wanders in.
I still have trouble dragging command cards to the table, but I can at least reveal those in my hand as I play them, and move them to the bottom row. That requires my opponent to open my hand to see what's been played, which is sub-optimal, but works a bit at least. It can also mess with timing a bit -- last game I played I ran Officer's Timing, but was in the middle of revealing it in my hand when my opponent declared his Agile conversion from an EJet. Not the end of the world, and he jumped the gun a bit by adding a modifier before I had a chance to, but it would've been nice to be able to move the card instantly so he could see that I was doing something in the add modifiers step.
I guess my question is this: Is there a known issue here, and any workaround? Like a hotkey to send a card from hand to map? Anyone else game on macs and have this problem (or not have this problem)?
My guess is that the heavily-windowed Vassal game is just optimized for, well, Windows OS. I'll probably keep playing even as-is, but would love to get past this set of glitches.
