CGminer Gridseed help. Program freezes, but still accepts shares

[Cryptomuncher]

So I've been using the modded CGminer for awhile on my 22 Gridseeds. Up to 15 griseeds, it recognizes, loads and shows current stats. When I start 16+ miners, it shows GSD 21 added (for 22) and the cgminer screen freezes, but still shows accepts in my pool for all 22. Any reason for this? It would be nice to see if i'm having any HW errors or rejects for each miner. Right now I'm just assuming they all are working right. Also, how do I get the cgminer screen to expand to show all miners? The box is too small past 12 miners and doesn't show them. Thanks!!
