Apparent bug in WebObs

For some of the stars that I observe, the Chart ID is not preserved from one WebObs session to the next, and I have to dig through my stack of charts to find the Chart ID and re-enter it each time. It appears to me that this situation is confined to stars having very long names or designations (e.g. CSS100217:104411+211307, MASTER 072948.66+593824.4, SDSS J100515.38+191107.9 - each 23 or more characters in the name). I do not have to re-enter the Chart ID each time for VSX J012059.6+325544 (20 characters) or objects with shorter names. I thought this might be some browser/cache issue but clearing the cache on my computer did not resolve the situation. thanks, Carey (CCY)
