I have noticed that when already on the map, the only really safe way to minimize OP and come back w/o issues is to be in the shipyard, view a ship, then minimize and come back.
As far as actual reinstall problems, not sure without more details on your problem.
You may need to delete all folders, etc and do a complete fresh install, though, not just a unistall and reinstall.
I have also noticed that, according to the webmap, you have quite a collection of ships:
K-D5D) HMCS Webmap
(I-CCY) HMCS Webmap
(K-D5D) HMCS Webmap
(K-D5D) HMCS Webmap
(K-D5D) IKV Distant Thunder
(R-KCNF) HMCS Webmap
(K-F5DB) HMCS Webmap
(K-D5D) HMCS Webmap
(K-DWD) HMCS Webmap
(K-DWD) IKV Distant Thunder
(K-G2R) HMCS Webmap
(K-APT) HMCS Webmap
(R-FH-E) IKV Distant Thunder
(K-E3E) IKV Duelslayer
(R-FSML) HMCS Webmap
(K-FSML) HMCS Webmap
(K-DWD) HMCS Webmap
How the heck did you manage that...?
