Let's say you've just resolved a problem and you say the following:

It has been troubling me because sometimes I saw past tense being used and I always wondered why.

I'm quite certain the tenses are correct but wonder if I can say the following

It has been troubling me because sometimes I see past tense being used and I always wonder why. (and maybe
add, "Now, I feel the world has been lifted off my chest")

What do you think? If it is acceptable, how natural is it?
Thanks!

Fine - apart from the comma in b, which should be:

'I'm so glad! What a relief. The design of the control system has been troubling me, and sometimes when I look at the equations I wonder why the second variable is a function of y2.'
I would say it's ok if you've been designing it up to now... and it's been troubling you.
But if you gave up designing it at a certain point in the past, I'd use the past... it had been troubling you.
Again, just my opinion. I don't understand the present perfect continuous either, I just pretend I do! Emotion: stick out tongue

badegine,

What do you think of the following?

'I'm so glad! What a relief. The design of the control system had been troubling me, and sometimes when I looked at the equations I wondered why the second variable was function of y2.'

What do you feel when you hear it in the context mentioned before? Try to avoid using grammatical terms in your explaination. I would like to know how you feel as a native speaker (I think you're, right?).

Also, which tense would you prefer? I'm trying to see whether it's a matter of preference.

Thanks in advance!
Hi,

I would like to hear what badegine would say.

I think your sentence is good and conveys the sense of your troubling days over the design of the control system is OVER.

Your sentence:

'I'm so glad! What a relief. The design of the control system had been troubling me, and sometimes when I looked at the equations I wondered why the second variable was function of y2.'

I think this is not good since the tenses are not consistent. Am I correct? Whenever I use a past perfect continuous, I look for a clue word/phrase (clause too?) that indicates something has been occurring some time before something else like "He had been watching TV until his father came home at 8 p.m. yesterday evening." -- Here "until his father came home at 8 p.m. yesterday evening" is a clue word or phrase.

And according to that, this wouldn't be correct. Am I right?

'I'm so glad! What a relief. The design of the control system had been troubling me, and sometimes when I look at the equations I wonder why the second variable was function of y2.'
Hi Anon, I don't understand the need for a 'clue phrase' phrase explanation you provided. You mean you don't use the past perfect continous tense without an additional phrase like what you suggested in your example but you have no problem with the present perfect continous standing alone? Interesting- something new to me.
