Nope...

Lets say we had ten thousand captures after this;

Loop:
TMR1H = 0    'Clear 8-bit register                              
TMR1L = 0    'Clear 8-bit register
capture = 0  'Clear Timer
'SEROUT2 LCD,84, [Prefix,CursorPS,0,"Capture ", dec Capture," ",DEC Period]
Start:
      If Capture = 0 then
         Goto Start
      endif

      T1CON.0=1
      Capture = 0 
      
CaptureLoop:
  If Capture = 0 then 
    'SEROUT2 LCD,84, [Prefix,CursorPS,0,"Dont Capture ", dec Capture," ",DEC Period]
    Goto CaptureLoop
  endif
T1Con.0=0  
period.LowByte=CCPR1L
period.HighByte=CCPR1H

They would all be zero since TMR1 was disabled after the T1CON.0=0.
Once period = CCPR1L & CPR1H it's a done deal until the next capture,
and Timer1 is re-enabled.

Capture works wether or not Timer1 is enabled. It just returns 0 if it's off.

Yet - I may be missing something...
