perforce - p4v not looking in correct root directory for workspace -


i trying history workspace in p4v. believe changed root directory @ 1 point, , updated root shown in workspace info p4v , command line. however, following when attempt review history.

path 'c:\path_to_old_root\...' not under client's root 'c:\path_to_new_root'. 

the perforce command run is:

p4 changes -s submitted -l -m 100 c:\path_to_old_root...

additionally, when looking @ workspace in selectro on left side pane shows c:\path_to_old_root\ local directory.

i unsure why generating command/determining local directory use in manner is.

not sure why occurred, appears files in .p4qt directory not correctly updated. based on suggestion deleting said directory might helpful, searched directory occurrences of old root path , replaced them new root path. appears have corrected problem.
