Blogger comment section doesn't always work for me.

It isn't every time... just hit and miss... sometimes I can leave comments.. sometimes not. Just tried on Mary's blog. The thingy came up for me to sign in (which I did) and tried to post and it sent me right back to the sign in thingy again. When it does this, I give up and move on to the next blog.
Even though I couldn't comment I did enjoy reading the post. (Mary and the bird playing in the water). It happens a lot. If you can see that I have visited but didn't comment that's probaby why. (couldn't comment on Margaret's either.)Do you think that Blogger made a change and I didn't get the memo? LOL
