Error while feeding in details in tds/tcs schedule of itr

Anybody using income tax ITR excel utllity??

I have been using income tax ITR excel utllity for filing e-returns. and have regularly (oh yes!! very regularly) faced this problem. Every time I try to insert new rows in Schedule DDT_TDS_TCS (for example, that of ITR 6), the tab meant for inserting the rows (which says "click here to insert rows in sch TDS2) enlarges itself (so much so that it literally overwrites the previously fed in data) and hence no new data can be added.... The only solution that I'm left with is, fill in a new ITR importing the previous one (not necessary it works every time...). Any body facing a similar problem?? and how do you deal with it??
